In recent times, gamification has become a popular technique to aid online communities stimulate active member participation. Gamification promotes a reward-driven approach, usually measured by response-time. Possible concerns of gamification could a trade-off between speedy over quality responses. Conversely, bias toward easier question selection for maximum reward may exist. In this study, we analyze...
Lack of effective usage examples in API documents has been proven to be a great obstacle to API learning. To deal with this issue, several approaches have been proposed to automatically extract usage examples from client code or related web pages, which are unfortunately not available for newly released API libraries. In this paper, we propose a novel approach to mining API usage examples from test...
In this paper, we propose a reversible data hiding method based on pixel difference histogram shifting and ripple strategy. Because the local area has similar pixel value distribution in the natural image, the pixel differences will be narrowed down within a small range. The ripple strategy is used to calculate the pixel difference using the pixels in the outer ripple to subtract the pixels in the...
This paper proposes a topic-based method to reflect calls and proximities simultaneously into finding interaction patterns from a mobile log. For this purpose, the proposed method regards calls and proximities as a homogeneous information type that are drawn from the same temporal space expressed by the same distribution, but with different parameters. The number of proximities in a mobile log usually...
Due to the rapid increase of information in the World Wide Web, there exists an explosion of information on the Web that may overwhelm the common Web user. The Web user may find it quicker or more efficient to browse the Web by reading summaries of Web sites. This paper proposes WebSum to compress Web site content into a summary. WebSum is an enhancement of the SumBasic algorithm, that was mainly...
Users often visit many stores while they compare merchandise in order to purchase the merchandise or merchandise related to it. Given a service providing information such as location of these stores, they can reduce their time and effort spent by wandering around them because they can go straight to these stores. And they can obtain new purchase opportunities because they can know what kinds of related...
In this paper, we study how to choose the combination coefficient of the combined field integral equation (CFIE) by comparing the iteration steps in solving the relevant matrix equation using the conjugate gradient iterative method. The tentative principle to choose the CFIE combination coefficient is given in terms of the calculations of two typical models, a cylinder and a NASA almond, with different...
We have developed the multimedia player based on the Internet. This player can display an image received from the mobile phone or the Web. Also, it can play a received MP3 file. In top face, we can control a volume, shift key for image presentation, display function, so on. And it includes hardware memory for saving a moving image data of the big size.
Emergent knowledge does not come from a particular document or a particular knowledge source, but comes from a collection of documents or knowledge sources. This paper proposes a system which combines the social Web contents and the semantic Web technology to process the emergent knowledge from the blogosphere. The proposed system regards blog postings as experiences of people on particular topics...
Computer-games research has opened a door to a multi-discipline domain across artificial intelligence, computer-aided design and computer graphics. Chinese chess is one of the most popular board games worldwide and many researches on move generation, position evaluation, searching, opening and endgame play, have been developed. However, few work has been done in the basic representation of Chinese...
Most current web application use HTTP (Hyper Text Transfer Protocol) and TCP (Transmission Control Protocol) to retrieve objects from the Internet. SCTP (Stream Control Transmission Protocol) is recently proposed transport protocol with congestion control mechanism similar to that of TCP. Waiting delay is an important performance criterion for when transferring web object over the Internet. In this...
We have implemented the CID(Caller Identification) system based on the web Internet. The system can connect a wire or wireless phone to the computer. A transmitting signal of the phone before starting the voice communication be displayed on PC, and connects with the GPS. Here the GPS signal informs the position information of an object with a satellite. Then the CID presents several information of...
Online auctions are increasingly becoming the platform of choice for dubious sellers to engage anonymously in fraudulent behaviour. While researchers are noble in their efforts to devise mechanisms to counter auction fraud, they are often frustrated by the lack of available auction data. Such data is an invaluable tool to gain insight about fraudulent traits and for testing proposed security remedies...
Machine translation systems have various problems although they have been developed continuously. Especially, in Korean-English translation system, zero pronoun problem is an important problem, since omitted subject or object Korean are must be restored in English. In order to solve this problem, various methods have been proposed. In this paper, we focus on the gender determination problem in Korean...
